In 4 studies we tested the efficacy of artificial, letter based pronunciatio ns to support poor spellers in building up stable orthographi c representations. In all 4 studies children's spelling skills improved during training. However, the experimental group who was trained to articulate a spelling pronunciation before spelling the word did not show a larger benefit than a well matched control group receiving the same type of training, but without spelling pronunciations. Thus, in a series of well-controlled studies using different sets of training words and slightly different training methods spelling pronunciation s turned out not to be of specific help to acquire word spellings. On the contrary, knowledge of spelling pronunciations seems to be a by-product of acquiring the correct spelling.In a recent study, Landerl, Thaler, and Reitsma (2007) could show that German speaking children are able to use spelling pronunciations to build up stable orthographic representations for irregular word spellings. Spelling pronunciations are letter-based pronunciations that use the regular German grapheme-phoneme translation. Examples of spelling pronunciations for irregular words are /ska te b ard/ for Skateboard or /bu si nes/ for Business. The training was administered to the 11-year old participants in 10 daily sessions. Both, poor and age-adequate spellers were better able to learn the spellings of foreign or loan words when they were trained to pronounce the spelling pronunciation before spelling the word than matched control groups
